• web_search

  Search the live web and get ranked results with title, URL, snippet and published date. When to use: an agent needs current facts, news or links that are not on chain - 'what is the BTC fee market saying today', 'recent Zcash governance proposals', 'find the docs page for X'…

• web_fetch

• web_crawl_async

  Submit a same-host crawl as an asynchronous job and return a job_id immediately. When to use: you need more than a couple of pages and cannot hold a long HTTP request; submit here, then poll web_crawl_job until status is done, failed or cancelled. Do not use: for one page…

• web_diff

  Fetch a page now and compare it with the previous snapshot of the same URL, returning whether it changed and a unified diff (no LLM). When to use: monitoring a page for updates - prices, docs, policy pages, SEO titles/meta; first call stores the baseline, later calls return…

• web_monitor_set

  Create a scheduled change monitor for one public URL: the server re-fetches the page on an interval, stores a new snapshot and records a diff event whenever the readable text changes. When to use: the user wants to be told when a page changes (price, docs, policy page, job post…

• web_monitor_list

  List the scheduled change monitors owned by the calling IP, with latest/next check time, last title or error, and the 5 most recent change events. When to use: after web_monitor_set, poll this instead of re-fetching the page; or to show the user what is currently being watched…

• web_monitor_delete

  Delete one scheduled change monitor owned by the calling IP (its event history is removed too). When to use: the user no longer needs to watch a page, or the per-IP monitor limit was reached. Do not use: to pause a monitor temporarily - there is no pause; delete and re-create…
